Integer structure illustrates how primes represented by 4R1 + 1 are equal to a sum of squares. Such primes are in Class ̅14 ⊂ Z4, a modular ring. The rows of squares in Z4 are well defined and this permits equalities for the primes to be derived from the integer structure. These equalities have the forms R1 = r1 + r0 where r1 = 3n(3n ± 1) or 2 + 9n′(n′ + 1) and r0 = 22q(12m(3m ± 1) + 1) or 22q(4(2 + 9m′(m′ + 1)) + 1), with q = 0, 1, 2, 3,… and n, m yielding the pentagonal numbers, and n′, m′ the triangular numbers. When n = m the equations are similar to Euler’s prime equation. Equations for the remaining primes, in Class ̅34 may be obtained in the same manner using p = y2x2 with (y x) = 1.

This paper considers some generalizations of the Fibonacci and Lucas numbers which are essentially ratios of the former, and hence not necessarily integers. Nevertheless, some new and elegant results emerge as well as variations on well-established identities.

Some results on infinite power towers
Original research paper. Pages 18—24
Full paper (PDF, 223 Kb) | Abstract

In the paper the infinite power towers which are generated by an algebraic numbers belonging to the closed interval are investigated and an answer is given to the question when they are transcendental or rational numbers. Also a necessary condition for an infinite power tower to be an irrational algebraic number is proposed.
